Referring to Figs. I and Il, 1 designates a suitable base adapted torest on the grate of a stove or other-suitable support. An oil cup oropenftopped oil reeeptaole 2 is formed on the top oiA a tubular support3 Whicfli eX- tends upwardly 'from base 1 and has an interor passageextending through. the oil receptacle, said oil receptacle being formedan annular @up sur?.y :undinff said passa e. Lateral perforatons .5extent through t ris tubular support. Surrounding the tubular support 3is a rim or Wall E which is desirably loose or removable, resting on thebase 1 and laeld .in place by pins or lugs 'Z on said Abase. The spacebetween said rini 6 and tubular support 3 'forms an exterior passa e 8which extends ulnvardbT around the tuular support :uid around the oilcup, and air passages or lroles 9 are provided in the buse `1 eornredini-.fusing with said outer passage S.

The air passes from the inner passage 4to the Vaporizing Chamber or space over the oil cup, through theopenings Y The cap 1() is provided with lugs 14 on s under side whichengage outside of lugs .l to hold the cap .in central position, theselugs 14 being lugs 11 in all 'rotative vpositions of the cap 'whileallowing free draft 'passage between- 5 and removed.

f "l the burner above described opera-tes satisfactorily, burning with aclear flame when the stove is closed, it is liable to smoke somewhatwhen a stove lid is removed, owing to diminution of suction andconsequent 'decrease in flow of air between the oil cup and the cap.rFhis may be remedied by the provision of an auxiliary draft iue 28shown in Fig. VI extending from beneath the burn/er base 1 to somedistance below the stove, for example, through the floor 29 into the`cellar or room beiow. This auxiliary draft flue being attached to aplate 30 on which the burner; base rests, becomes heated `by con#duction and an' upward draft is produced therein which will maintain aflow of air vthrough the burner sufficient to y roduce thev carburetingeect evenfwhen t estuve is opened.

inastove or fire-pot, indicated 9.13.23 in- Fig. I, its base 1 acting asacl'osure for said fire-- stove to pass through the burner passages;Oil'bein turnedon till thecup 2 is full and preferab' y overflows, itislighted at any convenient point, for example, atthe wick 18 if thelatter be used. The lame 4heats the .tubular support 3,' leap 10 ahd in-A closing ring Gand the regular eom'bustionof thevburner will thenproceed.. The eater part of the inming air will pass-up trough the inner`air passage 4 and will be deflected B5' bythe cap 10H50 as to pass overthe oil in the In use, the burner will generally be placed' pot'so as toforce all the natural draft 'of the quickly i cup 2 and out through theannular opening 'between theexternal lips of the .cap 10 and the oilcup, and the oil vapor which arises froml theoil in the cup is instantlymixed with and carried out by this current of air. The mixture that thuspasses out from beneath the deecting cap, meets the current of airpassing upwardly in the outer passage y 8 and-is deiiected upwardly,burning w ith a cup-shaped, clear, hot flame.

J will be understood that the air which passes up both the inner ,andouter passages aforesaid will be heated by the adjacent metal surfaceswhereby such air is rendered .more eflicient both in taking up the vapor`and in the combustion thereof. The outer, \inclosing ring 6, serves toabsorb part of the heat from the flame and to carry down and transmitsuch heat, by radiation and condution to the other parts. Any. surplusor excess of oil supply thatmay run .over the rim ofthe oillcup 2`Will.be partly vaporized inpassing down over the flaring lip surface lendifany remains, it will fall on the disv tributer plat-e or ring 17 and'will thereby be spread out and vaporized. The object of the flaringsurfaces at '1-3, 1.6, is to prevent the oil from falling to the base inlarge drops and to force the oil to spread out and expose a largesurface to the heated air and metal.

If the excess of oil'is beyond the vaporizing capacity at both thesurfaces at 13, 16, the

unvaporized portion ,Will fall into the catchbasin or cup 17 Where thevaporization will be completed It may be stated that as regards the oilthus vaporized at 13, 16 and 17, the air passing up through the outerpassage 8 serves a slmilar function in mixing or carbure-ting tothatdcscribedin connection with the air passing up through the innerpassage 4.

Owing tc the vdifferences or variations in the natural draft ofdifferent stoves and their .chimneys it fis desirable' to rovide means"for adjusting the liow ofair om the inner passage over the oil'tocompensate for such difference in draft'.4 To this end I make the[proportions of the'parts such that the most efficient actioniis secured'Withra Weak draft and in case the "naturaldraft of the stove toWhich-.the burner is to' be applied i's stronger than such-weak draft .Iapply 'Washer 21 above referred to, w ose thickness should be sufficienttodiminish. thel draft' (proportionately to suchv lncrease of;

vopening draft-an maintain. the proper condition of suction through thevaporizing chamber or space over the oil draft.

' Such chan fe of draft may also be effected by use of different capswith' differently shaped external lips so as to .vary the draft opening.l
